I got my first kindle 5 months ago (and I immediately registered here for the jailbreak). I have nine of them now. So I only have 5 months of experience (or 5 years crammed into 5 months if want to think of how I apply myself to things that interest me), so I am practically a beginner myself. You can see from my early posts until now how I go about studying this stuff. Not counting MANY (too many?) IRC messages I posted (in the IRC archive), my PMs and posts here are over 1500. Unfortunately, the "view all posts by this member" only shows 500 posts, so even I cannot find my old posts. I *really* wish they would fix that. Anyway, you can learn this stuff just like I did, but it takes time, dedication, persistence, and more time.
P.S. For each message that I posted, I *read* many, many messages. I have also read all the manuals and other offsite resources I could find (i.e. Parallel Procrastination et. al.). So I could easily have read a million words dedicated to the kindles, in just the past 5 months. (I have over 10,000 books in my collection and I have read most of them before I was 30 -- I always carried 3 books with me everywhere I went in the "pre-Google" era). You just need to decide how you want to spend your time. We rarely watch TV (although we DID buy a $1600 USD TV for Christmas). Really, if you want to be a kindle expert you can, but only at the expense of other things in your life (such as TV)... You decide.
